Model

In projects for streetcars, the overhead catenary designs lead to elements with highly non-linear behavior, with large deformations that require correct structural analysis so as not to put the line out of service.

After an exhaustive comparison of the software packages on the market, SDEA Engineering Solutions found the answer it needed in Dlubal’s RFEM software. This program has a very good learning curve (as easy to handle as an Excel sheet), a large number of tutorials, and extensive ad hoc documentation. In addition, its team of technicians deserves special mention, as they worked hard to solve all the questions that arose during the initial phases of the project.

From a technical point of view, the option of creating fully parameterized models was essential, from the geometry, to the loads, to the final result output. Another fundamental point was the software's intuitive and agile menu for defining action combinations and the fact that many of them were predefined, based on the most relevant standards of a wide variety of countries.
